The Maelstrom Mod introduces three new races to the Sins of a Solar Empire Universe. They are independent of the original races and have unique strengths and weaknesses. Maelstrom is available Rebellion, Diplomacy, Entrenchment and Original Sins.
Brilliant integration of new factions and new ships. Each faction is actually unique across the board and the original factions have a fresh feel. Some of the models could be a bit sharper but that is literally one or two and many are excellent. I think the Damocles is an unbelievably awesome unit and would play this mod for that ship alone! Outside of Star Wars mods (personal preference) I think this is the best SoaSE Rebellion mod going and I have tried quite a few.
